답리작 유휴 농지에 바이오 디젤의 원료인 유채의 다수확 재배법을 구명코자 시험하였던바 그 결과를 요약하면 다음과 같다. 50×20 cm 조파는 종실수량이 298 kg/10a인데 비하여 50×15 cm 점파구에서는 1.000 kg/10a의 표준 퇴비 시용구가 361 kg/10a로서 21% 증수였고 1.500 kg/10a의 퇴비 50% 증비구에서는 422 kg/10a로서 42%가 증수였으며 50×30 cm의 이식구에서는 1.000 kg/10a의 표준 퇴비 시용구가 392 kg/10a로 32% 증수였고 1.500 kg/10a의 퇴비 50% 증비구에서는 455 kg/10a로서 53%가 증수되어 가장 수량이 높았으며 바이오디젤 원료인 수유량에서도 50×30 cm 이식, 50% 퇴비 증시구에서 200 kg/10a로서 56%가 증수되어 가장 수유량이 높았다.
Abstract
In order to find out the optimum compost powder, fertilizer level and planting method of high yielding F1 variety, Cheongpungyuchae, this experiment was conducted with 2 compositions of compost powder level and 3 different planting method at the experiment paddy field of Mokpo Experiment Station, National Institute of Crop Science, RDA. Cheongpungyuchae, rapeseed variety was grown under different compost powder level and planting method with the highest yielding variety. Yield components such as ear length, total branch, number of pods per ear and oil content were highest at the plots with compost powder 1,500 kg/10a at level and planting method, Oct.30, transplanting with 50×30 cm. Judging from the results reported above, at optimum compost powder level and planting method of rapeseed seemed to be 1,500 kg/10a compost powder and transplanting method with 50 cm row spacing and 30 cm planting space. Key words - Rapeseed, Compost powder level, Planting method, Yield, Oil extration yield
